Man does not live by caffeine alone.

A teenage girl in County Durham, in the UK made the mistake of knocking back seven double espressos - Wow!

She had to be rushed to hospital when she developed a fever and started hyperventilating.

It seems she was under the impression the coffees were single measures and overdosed on caffeine.

She said: ” I was having palpitations, my heart was beating so fast and I thought I was going into shock”

"My nerves were all over the place.”
